<br />
<br />
<br />For the rechargeable (generally refers to the lithium battery) from the protection of the integrated circuit board. Lithium battery (rechargeable type) so need protection. 
<br />
<br />
<br />As the lithium battery itself determines the material itself can not be overcharge, over discharge, overcurrent, short circuit and ultra-high temperature charge and discharge, so lithium battery lithium components will always follow a protective resistor with a sampling resistor and a current fuse.
<br />
